The topic of DVD-Audio/SACD and HD DVD/Blu-ray was discussed a few months ago in my Advanced Digital Mixing class a couple months ago. Like you said Gonk, they came out at around the same time. This certainly set up competition right away. What's more is that players that offer support of both only pro-long the life of the loser. The same thing is beginning to happen with HD-DVD and Blu-Ray. It's the DVD-Audio/SACD war all over again.
